Abstract
Official abstract text for this publication.
A system and a method for pretreating an aluminum assembly includes selecting a blank having a thin film pretreatment layer and a lubricant coating applied to a surface. The blank is formed to a desired shape and an adhesive is applied to a selected portion of the surface. A cleaner is applied to the assembly to remove the thin film pretreatment layer and the lubricant coating from the surface except at the selected portion and a zirconium oxide conversion coating is applied to the assembly before painting.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for pretreating a part formed from a blank that is coated with a pretreatment layer and a lubricant coating, the system comprising: an adhesive applicator that applies an adhesive that covers the pretreatment layer and the lubricant coating on a portion of the part a first immersion bath that applies a cleaner to the part to remove the pretreatment layer and the lubricant except the portion of the part covered by the adhesive; and a second immersion bath that applies a conversion coating to the part. 2. The system of claim 1 wherein the pretreatment layer and the lubricant coating are applied to a coil. 3. The system of claim 1 wherein the pretreatment layer is an aluminum hydroxide layer, and wherein a layer containing phosphonic acid or phosphinic acid compounds is bonded to the aluminum hydroxide layer. 4. The system of claim 1 wherein the lubricant coating is a dry lubricant. 5. The system of claim 1 wherein the lubricant coating is a dry lubricant that is a blend of mineral oil and paraffin wax. 6. The system of claim 1 wherein the portion of the part is a hem flange. 7. The system of claim 1 wherein the part is an assembly and the portion of the part is a portion of the part that is joined to a second part. 8. The system of claim 1 wherein the conversion coating is a thin film zirconium oxide coating.
